At present, the properties view for forms defaults to category. I personally prefer to A-Z option, so i set the view to this. This setting appears to be kept in the one session, but when you quit PS Studio and load again and the project, it resets to category view, and I have to change this setting again.

It would be helpful for the view order to be saved in the project file so that when a project is loaded again, the sort order is restored.
